A Review of Virtual Sensing Algorithms for Active Noise Control
Traditional local active noise control systems minimise the measured acoustic pressure to generate a zone of quiet at the physical error sensor location. The resulting zone of quiet is generally limited in size and this requires the physical error sensor be placed at the desired location of attenuation, which is often inconvenient. To overcome this, a number of virtual sensing algorithms have b...
متن کاملActive noise control at a moving virtual microphone using the SOTDF moving virtual sensing method
Traditional local active noise control systems minimise the measured acoustic sound pressure to generate a zone of quiet at a physical error sensor. The resulting zone of quiet is generally limited in size and as such, placement of a physical error sensor at the location of desired attenuation is required, which is often inconvenient. Virtual acoustic sensors can be used to project the zone of ...
متن کاملOptimal virtual sensing for active noise control in a rigid-walled acoustic duct
The performance of local active noise control systems is generally limited by the small sizes of the zones of quiet created at the error sensors. This is often exacerbated by the fact that the error sensors can not always be located close to an observer’s ears. Virtual sensing is a method which can move the zone of quiet away from the physical location of the transducers to a desired location, ...
متن کاملVirtual sensors for active noise control in acoustic-structural coupled enclosures using structural sensing: robust virtual sensor design.
The work was aimed to develop a robust virtual sensing design methodology for sensing and active control applications of vibro-acoustic systems. The proposed virtual sensor was designed to estimate a broadband acoustic interior sound pressure using structural sensors, with robustness against certain dynamic uncertainties occurring in an acoustic-structural coupled enclosure. A convex combinatio...
متن کاملImprovement of Active Noise Control Performance by Changing Reference Signal
The LMS (Least-Mean-Square) algorithm, which can obtain the complex transfer function in real-time, allows the changes of noise characteristics and the environment of system, thereby maintaining the convergence performance. Therefore, many algorithms based on the LMS algorithm have been modified to solve for some practical considerations, and the FXLMS (Filtered-X LMS) algorithm has been widely...
